Specification of Letters Patent. I Patjgntgd June 2}? jggg Application filed February 6, 192-0. Serial No. 356,678.

To all whom. it. may concern:

Be it known. that I, VERNON C. Gnrz, a citizen of the. United States, and a resident of Lebanon, county of Boone and State of Indiana, have invented a certain new and each other whereby the entire incubator canbe readily and easily assembled or knocked down by lifting off each successive unit beginning with the top. This construction will enable the incubator to be easily and quickly renovated, sterilized and cleaned aside from the advantages in manufactun ing, shipping and storing. j

The full nature of this invention will be understood from the accompanying drawings and the following description and claim.

Fig. 1 is a central cross sectional view of the incubator and the heat producing means associated therewith, and is taken on the line 11 of F 7. Fig. 2 is a top plan view of the same. Fig. 3 is an enlarged'detailed view of the bracket leg for supporting the egg containing tray. Fig. 4: is a side view of the same. Fig. 5 is a sectional view of the bracket leg taken on the line 55 of Fig. 3. Fig. 6 is a reduced end elevational view of the incubator and heat producing means and shows in detail the temperature regulating means. Fig. 7 is a horizontal sectional view of the incubator taken on a plane passing through the heating coil. Fig. 8 is an enlarged sectional View showing in detail the slide construction for regulating the temperature of the incubator.

In the drawings 10 indicates the outer wall of the improved incubator provided with a detachable cover 11 and a heat producing element consisting of a lamp 12, detachable hood 13 and a suitable boiler 14. In the present instance the incubator is shown cylindrical in form, and the outer wall 10 thereof is composed of an outer cylindrical shell provided with a pair of par allel inwardly extending circular flanges 15 and 16. Positioned concentrically within said outer shell is an inner shell 17 the same being provided on its upper and lower edges with outwardly extending parallel and. circular flan esIS and;1 9, said flanges. abutting radially t efianges and 16 and the outer shell. 10, as shown most clearly in Fig. 1. YVithin' the annular. channel formed by said shells and abutting and engaging circular flanged portions, there is. provided suitable insulating .material. 20. From. the foregoing construction it will be understood that. said parts are of simple construction and may be readily assembled. The cover 11 is herein shown substantially dish shaped or provided with a surface sloping downwardly from the. center thereof to the outer edge. The outer.

circumferential edge of said cover 11 is pro- I A vlded with av downwardly extending circular flange 21, said flange having a yielding en gagement with the upper edge of the outer shell 10 to close the same. The cover 11 may be provided wlth the usual central opening 22, the same closed by a transparentmember or glass 23.

Suitably secured. to the inner shell .17 are a plurality of inwardly and'radially extending supporting bracket members 24. Beneath the same, and positioned, adjacent thereto and suitably secured to the inner shell 17, is an annular deflector. Herein said deflector comprisesa felt portion .25 supported by an inwardly extending sheet metal annular plate 26. Positioned above said deflector and supported by said bracket 24 is an annular heating member 27, said heater being provided with an outlet 28 extending through the tubular walls of said incubator and being connected with a suitable boiler element 14. Extending across said circular heating coil 27 and communicating at botlrendstherewith, is a tube 29, one end of said tube communicating with the circular coil 27 adjacent the outlet 28. The heated fluid passes into each half of thecircular tube-27 and continues around the same to the opposite side of the circular coil, whereupon both currents unite and return through the tube 29 to the junction of the circular coil 27 with the tube 28.

Positioned beneath the deflector plate 26 and substantially midway between the upper and lower edges of the tubular outer wall of the incubator, is an egg containing tray composed of screening 30 supported by suitable braces 31 positioned beneath the same, said braces extending to the edges of the screening and being suitably secured to a circular frame 32. The screening permits air to pass upwardly through the eggs positioned upon the same. The egg supporting tray is supported beneath said deflector plate and substantially in the mid dle of said incubator by means of a plurality of bracket legs suitably secured to the circular frame As shown clearly in Figs. 3, a and 5, the bracket legs are formed of a substantially corrugated strip of sheet metal, each corrugation being suitably cut away to provide the locking portions 3a and 35, as shown. The edges 36 of the cut away portions pass beneath the circular frame 32 and support the same. The portion extends upwardly adjacent the exterior portion of the circular frame 32. The upwardly extending portions 34 are bent outwardly, as shown in Fig. 4e. The portions 34; and 35 accurately secure said circular frame upon the bracket legs 33. Positioned beneath said tray and within the tubular wall of the incubator is a shallow pan or tray 37. The legs 32 are adapted to stand therein and said tray or pan, should the same be necessary, is adapted to contain water and the like to provide moisture for the incubator.

Extending through the shells 10 and 17 and the insulating medium is a circular opening 38, herein shown formed by ex- 7 tending the inner shell 17 outwardly. P0-

sitioned within the incubator upon the wall 17 are suitable guide members 39, which slid ably support a plate to, the same having an outwardly extending finger piece 41 for sliding the same to regulate the size of the opening 38. The opening 38 is provided to regulate the temperature of the air within the incubator, and also the amount of moisture therein.

Positioned adjacent the incubator and detached therefrom is the lamp 12, the same being positioned beneath the annular boiler 14,. the same being provided with a central conical heating surface 42. Communicating with said boiler is the outlet 28, the same being provided with a suitable vent 29 for the escape of steam and any-overflow. Positioned upon the upper surface of the annular boiler 14- is a suitable supply inlet 43, said inlet being suitably covered. The hood 13 is herein shown cylindrical in shape and is provided with a slot 44, the same being adapted to receive the outlet 28, as shown support said hood in spaced relation with said boiler. As shown in Fig. 1 said hood is of substantially greater diameter than said boiler for a purpose to be described.

In the top of said hood is a central open-- ing 46, suitably covered by a cap 47, said cap being movable from said opening by thermostatic means, presently to be described.

From the foregoing it will be understood that when the cap 17 is seated upon the hood 13 to close the opening 16, the heat from the lamp; 12 will pass upwardly engaging up'on the conical heating surfaces of the annular boiler 14 and then passing from said boiler and downwardly along the outside of the same. In this manner the heat generated is compelled to pass around the boiler, and the boiler, lamp and hood form a more eflicient heating element than has heretofore been used.

The thermostatic means for controlling the opening 26 comprises the usual disk members 18, the regulating arm 49 and the counter-balanced actuating arm 50, said arm being secured to said cover 4157 by means of suitable link 51.

The invention claimed is:

In an incubator the combination of a tulnilai insulated wall open at both ends, a detachable cover to be positioned upon said wall to close one end thereof, a detachable pan positioned in the bottom open end of said wall to close the same, a perforated egg supporting tray positioned within said wall and substantially filling the interior of said wall and supported intermediate the ends thereof, said tray being removable through the lower end of the wall, heating means positioned above the tray and adjacent the wall, and inwardly extending deflecting means beneath said heating means and above said tray to prevent the direci downward radiation of heat from the heating means upon the tray, said cover deflecting means and heating means being arranged to provide-access to the egg tray through the top.

In witness whereof, I have hereunto affixed my signature.

VERNON C. GETZ.
